What you all can do is to go to the town's courthouse and get a copy of the pet and livestock laws and ordiances. do not tell them that you are getting chickens but curious about it. Read it carefully because some terms will say EXCEPT so many feet from neighbors or acreage #. That would give you some leeway with the EXCEPT word even they prohibit or unlawful. If you do get a copy of the the ordiance and still don't understand it, bring it on to here, type it out for us and we can figure out what you can have or what you are restricted with.
Good luck!
